B36CD50A is the model number for the refrigerator.
Don't know a lot about Bosch as they're not friendly with releasing service manuals so I can only suggest that you turn off the power to the refrigerator, open the door and let it defrost naturally. Bit rough if you have a lot of food, frozen and fresh, I know
Have plenty of towels handy ;-)
Once free of ice you may have a better chance to find out what's happening with the ice maker e.g. does it fill, freeze, dispense etc
Applying too much heat using a hair dryer etc may damage the ice maker and/or the freezer lining.
It seems that there are two model variants for the refrigerator. If you do find out what the problem is e.g. it may be a faulty ice maker etc here's a link to a parts supplier that may be useful.
It looks like the same parts are used in both model variants. Find the part in the relevant parts diagram and then you'll see the part number for the part. This is the manufacturer's part number. Search online using that number to find suppliers that suit you best.
